MKS SERVO42A Control Board Kit for Nema 17 CL Stepper Motor

The MKS SERVO42A V1.1 is a brilliant design from MakerBase that takes the best parts of both stepper motors as well as servo motors, to create a closed loop motor that not only offers the high speed and holding torque of a stepper, but also the near-perfect positional accuracy of a servo as it continuously reads its own position after moving, before making on-the-fly adjustments so that the output steps match the input commands.

This kit of the MKS SERVO42A V1.1 board module gives you the extra bits to go with your NEMA 17 stepper motor. Without the motor, this kit works well as an assembly of spare parts or a great way to adapt a stray NEMA 17 stepper motor. With the MKS SERVO42A board, this motor turns clever, making a loss-free stepping motor, using a closed loop system with a positional sensor for on-the-fly adjustments as it spins. This means that even when the motor misses a step, it can easily spot that small mistake and rectify it accordingly before it goes too far. And because of this functionality, the MKS SERVO42A can greatly increase print speeds up to 200m/s on some 3D printers – without having to modify any firmware, commit to any major hardware changes or jump through any other loops just to get it working.

This kit includes the MKS SERVO42A module itself, a A4954 stepper driver, the cables, and peripherals you need to get started.With such fantastic functionality, loss-free stepping capabilities, incredibly high positional resolution and the ability to be integrated onto almost any motherboard with interchangeable stepper Drivers, we feel that anyone who loves 3D printing will be eager to give this new kind of stepper motor a try.

Please Note: This kit does not include a NEMA 17 CL stepper motor. However, we do stock a version with everything included, so be sure to check out our NEMA 17 CL stepper motor with MKS SERVO42A to see if it would possibly suit your needs better.

Additional Note: The included MKS SV_EXT Adapter board is V1.1, which is perfectly compatible with the SKR Series Motherboards due to the included voltage converter featured on the underside.

Typical Applications for THE NEMA 17 MKS SERVO42A CLOSED LOOP STEPPER MOTOR:

The NEMA 17 MKS SERVO42A Closed Loop Stepper Motor is a brilliant motor that is perfect for high-accuracy 3D Printing, but is most ideal when used for applications like moving heavy Heated Beds and other components. As such, these are perfect for installing on large-format 3D Printers like the Creality CR-10 S5, as the heavy bed can easily lead to overshooting the steps or missed steps entirely. It includes a specialised A4954 driver adapter, an onboard Micro-USB port for configuring the motor via a computer, as well as a port with onboard buttons that accommodate onboard settings adjustments via an external 0.96inch display module.

These factors all make this one of the most advanced steppers that we’ve ever stocked, and we can’t wait to hear about your thoughts after trying this exciting new tech’!
